To all whom it may concern:

Be it known that I, HENRY T. ADAMS, a citizen of the United States, and residing at Chicago, in the county of (look and State of Illinois, have invented a new and useful Improvement in Motor-Cycle Attachments, of which the following is a complete specification.

This invention relates to improvements in motor-cycle attachments and more particularly to a-tandem attachment for passengers or luggage.

The object of the invent-ion is 'to provide an adjustable tandem cycles. so constructed that it may be attached to any desired make of motorcycle frame.

It is a further object of the invention to provide an attachment for motorcycles which is adapted to be adjusted to meet the requirements of cycles of various heights, and

' which also is adapted to be quickly attached to or removed from the motorcycle frame.

A still further. object of the invention is to provide means for adjustably attaching a cycle stand so that it will not be in the way when it is desired to adjust or remove the rear wheel, and which is adapted to be adjusted with respect to the adjustments of the rear cycle wheel.

Another object of the invention is to provide a tandem attachment adapted to be secured to either a vertical or a horizontal seat pillar,'according to the construction of the particular make of the cycle frame.

The invention consists of the matters hereinafter described in the specification and more fully pointed out'and defined in the appended claims.

As shown .in said drawings, A'indicates a cycle frame having braces a and a extending rearwardly and provided with a fork a in which is mounted the rear wheel A. by anv preferred means affording adjustment witli respect to the drive chain. as is usual in such devices.

Clamped upon the rear ends of the frame braces a and a is the attaching bracket B thereof having an offset portion. which to: gether with a similar oilset portion infaplate 6 adapted to be attached thereto,

forms a sleeve 7F adapted to receive said brace (1. Below said sleeve the bracket is provided with slots btadapted to receive'a Ubolt b to attach it to the brace a. Said slots provide means for attaching the bracket to various makes of frames. where the dis tance between the braces (1-41 varies. ()n

the upper end of said bracket is a slotted lug 7) to which thelowcr end of the adjustable Said uprighhas shown more clearly in Fig. 1. comprises an upper and a lower section indicated respectively by c-c. having overlapping ends in which are provided bolt apertures c for the reception of attaching bolts and permitting the upright to be adjusted as to length. The outer end of each section is slotted. asshown at in Fig. l5, and is turned outwardly to provide aledge 0 "lhe-lower end of thesection c is adapted to overlap the outer side of the lug b, and the bolt v("in-shown in Fig. 1, is inserted through the slots. in said lug and saidend, and the nut c" secured on the bolt. Said nut, as shown more clearly in'Fig. 16, is provided with a cylindrical boss 0 on its inner face behind which the ledge a engages and prevents the upright from becoming disengaged from the bracket should the nut become loosened. When, however, it is desired to remove the upright it is only necessary 'to retract the nut sufliciently to permit the ledge c to pass the boss 0 There are of course one of the attaching brackets and one of the uprights on each side of the wheel, and the upper ends of the uprights are bent inwardly and bolted. to a clamp D by the same kind of a joint as that afforded at the lower end of the, upright.

The frame is provided, as. shown in Fig. 1, with a horizontal seat pillar D, and to said seat pillar is attached a jointed clamp D which, as shown more clearly .in Fig. 5, is S shaped and comprises two practically U shaped members (id adapted to be pivoted together by a bolt 05 One member of said clamp is adapted to receive the seat pillar and the other member thereof is adapted to receive the forward end. of the seat bar (i the rear end of which is engaged in the clamp D, which as shown is flattened at its top at (i and the bar is likewise fiattened to prevent its turning. By means of the jointed clamp D it is possible to. adjust the upright C to vary the height of the rear seat D? which is secured to the seat bar d Handlebars D are adjustably secured to said bar by means of the adjustable handle bar clamp D which, as shown more clearly in Fig. 7, comprises a sleeve (Z slidably engaged on said bar and adapted to be held in place by set screws d. Onthe top of said sleeveis ajaw clamp (1 adapted to receive the handle bars and which is provided with a bolt seat d*' adapted to receive a bolt for tightening the jaw clamp on the handle bars. Should the cycle be provided with a vertical seat pillar D, asshown in Fig. 21, the joint clamp is bent at an angle to receive the pillar -and the bar, and when it is tightened by means of its bolt d? it will rigidly engage said parts.

Rigidly secured to the upright C and extendingdownwardly and forwardly therefrom is the footrest bar E which is secured to the frame brace a by means of an ad just able clamping plate 6, adapting the bar to be attached to said brace at varying angles, dependent upon the construction of frame and position of the upright. end of said bar E is turned outwardly to provide a foot rest a.

If desired the'seat and a luggage carrier F attached in its place. in Figs. 17 and 18, comprises a frame f having cross bars f" thereon on which the packages are laid. The forward ends f of said frame f are brought to ether and formed similarly to the upright (J, and are bolted to a clamp F adapted to be engaged to the The lower bar 03 may be removed Said carrier as shown more clearly seat pillar. To the rear cross bar 1 is attached a clip f adapted to be bolted to the upper end of the adjustable upright (l. G indicates a dress guard of any preferred construction. which is curved on its top to conform to the curvature of the rear wheel, and hangs down over the sides of the wheel to prevent the skirts from becoming entangled therein. Said guard is provided on its top with a pluralityof loops g adapted to receive a strap for fastening the device to the upright C above the wheel. vA plurality of said loops are provided so that the device may be attached to frames of various makes in which the angles vary. At the forward end of said guard is a strap y) adapted to fasten the device to the brace n. and a strap at the rear of the guard provides means for securing itto the mud guard G. The hooks at the bottom of the guard are adapted to be engaged in the apertures in the fork (1 The lower ends of the attaching brackets B are each provided with an elongated slot If in which the cycle stand H is adjustably mounted. Said stand comprises a U shaped member, the sides 72. of which are comprised of two sections and adapted'to be adjusted longitudinally. The; upper end of each side member is secured to the bracket B by means of a bolt and nut h''h shown in Figs. 12 and 13, the former of which is provided with a flattened shank 11. adapted to seat in the slot 6 and pre ent the bolt from turning, and the rt... is provided on itsinner face with a cylindrical boss It on which said side member is journaled. on the front side of each side member 71 is an upwardly and forwardly directed arm l1 adapted to engage beneath the brace a when the stand is in operative position. hen it is not desired to use the stand it may be turned rearwardly, as shown in dotted lincsin Fig. l. and secured to the spring catch H carried on the mud guard. By means of the attachment of said stand .in the slot If. the stand may be adjusted forwardly or rearwardly to accommodate various sizes of wheels and to compmisate for the adjustment of the wheel forwardly or rcarwardly in its yoke.

if preferred the fork a? of the cycle frame may be provided with a slot 7; corresponding to the slot 1) in the attaching bracket. In um event the stand would be connected in said slot 7) and the bracket B would be dispensed with, and the lower end of the upright C would be connected in the aperture g"; If preferred also, an auxiliary attach-. ing member for the cycle stand may be provided, comprising a clamping collar I, shownin F igst 3 and 4:, and which may be adjust-ably secured to the brace a on each side of the machine by means of a bolt passadapted to support the cycle stand when it is desired to remove the tandem attachments and the rear wheel. a

The operation is follows: The adjustable bracket I) is securedin position on the frame, and the uprights attached thereto. If the tandem attachment is to be used for carrying a passenger. the seat 'bar is attached at its rear end to the upper end of the uprightand at its forward end is attached to the seat pillar by means of the jointed clamp D. Owing to thejointed construction of said clamp D the upright C may beadjusted longitudinally to suit the convenience of the passenger. Thefoot-rest is clamped to the brace a by means of the plate c,'which permits of the upright bein swung forwardly or rearwardly on the bolt 0'', and also permits the attachment to. be applied to varying designs of cycle frames. When desired the luggage carrier may be attached in place of the seat bar and the articles to be carried thereon may be strapped or otherwise secured in place.

The cycle-stand is adjustably secured in the slot If in the bracket B which permits the stand to be adjusted forwardly or rearwardly as occasion requires. This construction permits of the rear wheel being removed or adjusted without interference from the stand. If it becomes necessary to remove the bracket the standmay be quickly attached to the bosses i, and where a specially designed frame is to be used with the tandem attachment the bracket B is dispensed with and the stand secured in the slot 1) in the frame.

Obviously the attaching bracket B affords means for securing the tandem attachment to any make of cycle frame and affords a very convenient means for attaching and carrying the cycle stand where it will not interfere with the adjustments of the rear wheel. Obviously also many details of form and construction may be varied Without departing from the principles of my invention.
